Abstract
Tunka-Rex is the radio extension of Tunka-133, a 1 km^2 air-Cherenkov Detector for air showers in Siberia. Tunka-Rex began operation on October 8th 2012 with 20 radio antennas. Its main goals are to explore the possible precision of the radio detection technique in determination of primary energy and mass. Each radio antenna station consists of two perpendicular aligned active SALLA antennas, which receive the radio signal from air showers. The preamplified radio signal is transmitted to local cluster centers of the Tunka-133 DAQ, where it is filtered, amplified and digitized. To reconstruct the radio signal it is crucial to understand how it is affected in each of these steps. Thus, we have studied the combined response of the antenna, with its directional pattern and the analog electronics chain, consisting of a Low-Noise Amplifier and a filter amplifier. We discuss the hardware setup…
